It is approximately 24.02 grams. Each mole of carbon weights 12.01 grams (one mole= enough particles to make a substance's weight in grams equal to it's atomic weight in amu; same amount of particles for every substance).
Just add the grams per mole mass of the constituent atoms. C---carbon = 12.01 grams 2 O---2 oxygens = 16.0 grams each, or 32.0 grams ------------------------------------------------------------------------+ = 44.01 grams per mole for CO2 ( carbon dioxide )
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
The atomic mass of carbon-12 is defined as 12 atomic mass units (amu). This corresponds to the mass of a single carbon-12 atom relative to 1/12th of the mass of a carbon-12 nucleus.
the atomic mass carbon is 12.011 g/mol 12.011/mol = the mass of one atom 12.011/6.022x10 raised to the power of 23 this equals 1.994520093 x 10 raised to the power of -23 this is the mass of one atom of carbon in grams.
To determine the mass of carbon on the weighing dish, you would need to know the total mass of the dish plus the carbon. If, for example, the combined mass of the dish and carbon is 5.0 g, then the mass of the carbon alone would be 5.0 g - 1.0 g (mass of the dish) = 4.0 g. Without the total mass, the mass of carbon cannot be calculated.
In terms of proportion of molecules that are carbon, 33% (formula: CO2 which means that there are 2 oxygens and 1 carbon). If you mean in terms of mass, then carbon is 27.27% of the molecule (Two oxygens at a molecular mass of 16 each, and one carbon at a molecular mass of 12) by mass.
First of all, carbon dioxide is a molecule and hence the question should be: What is the molecular mass of carbon dioxide? and the answer is 12 + (2 x 16) = 48
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
4 Carbon atoms in one molecule of Butane, times 2 because of two molecules, time the weight of one Carbon atom, which is 12 amu's (an amu = atomic mass unit, also known as a Dalton) equals 96 amu's.
An atom of Carbon with a mass of 15 and a +2 charge must have 13 protons. This is because the atomic number of Carbon is 6, so a neutral Carbon atom would have 6 protons. Since the atom has a +2 charge, it has lost two electrons, making it a cation, and giving it 2 more protons than electrons.
Just add the grams per mole mass of the constituent atoms. C---carbon = 12.01 grams 2 O---2 oxygens = 16.0 grams each, or 32.0 grams ------------------------------------------------------------------------+ = 44.01 grams per mole for CO2 ( carbon dioxide )
C2H6SO:C-2 (12.01)= 24.02H-6 (1.01)= 6.06S-1 (32.06)= 32.060-1 (16.00)= 16.00---------------------------= 78.14 g%C in C2H6SO= 24.02/78.14 (total mass) --> =.30739 (*100)Answer: 30.7% Carbon in dimethylsulfoxide.
The formula given shows that each molecule of the substance contains two atoms of carbon, twelve atoms of hydrogen, and six atoms of oxygen. Therefore, the gram molecular mass of the substance is twice the gram atomic mass of carbon plus 12 times the gram atomic mass of hydrogen plus six times the gram atomic mass of oxygen. In numerical terms, this is [2(12.011) + 12(1.00794) + 6(15.9994)] or 132.11. (Only five significant digits are justified, because only five digits are given for the atomic mass of carbon.). Therefore the mass fraction of carbon in the substance is 24.022/132.11 or 0.18183. Multiplying by 100 yields 18.183 % of carbon in the substance.
Most of the mass of glucose comes from carbon atoms, which are incorporated into the glucose molecule during photosynthesis. Carbon dioxide is taken in from the air during photosynthesis and converted into glucose, providing the majority of its mass.
The atomic mass of carbon-12 is defined as 12 atomic mass units (amu). This corresponds to the mass of a single carbon-12 atom relative to 1/12th of the mass of a carbon-12 nucleus.
The proportion by number of atoms in carbon dioxide is 1:2. The atomic weight of carbon is 12.011 and the atomic weight of oxygen is 15.9994. Therefore, the proportion by mass of carbon to oxygen in carbon dioxide is 12.011/(2 X 15.9994) = 0.37536 or 37.536 %, to the justified number of significant digits.
The atomic mass of carbon is approximately 12.01 atomic mass units.
